AQo in MP facing turn heat

[ghostface]

9 Handed at the 'Grid (lol) 2/4 Table

I open raise in MP, SB and BB call

Flop(6 SB) A 8 9 r
check, check, I bet, call, call

Turn(4.5 BB) T still rainbow
2x check, I bet, SB c/r's, BB folds, I call and hope for a Jack

River (8.5 BB) 6
SB bets, Hero ??

Can I call profitably?

With NO READS I dont see why not he could have AJ He also might Have Trip 8s or a straight but I dont think often enough not to call.
